Need a voice over for course material

Estimated duration: not set
Description: We need a voice over done on a power point presentation. the script is about 8.5K words over 70 slides, each slide to be recorded individually. Initially this is just for one course, however we do have a lot of work to do over the next few months and there may be an opportunity for ongoing work.
We will require a sample to ensure that the voice is what we are looking for.
